The function below models the correlation between the number of hours a plant is kept in sunlight (x) and the height (y), in mm, to which it grows: y = 2 + 4x what does the y-intercept of this function represent?

Y intercept of this function is 2 which is the height of a plant at the time x = 0 or the height of a plant when kept in sunlight.

Step-by-step explanation:

In the given function y = (2 + 4x), x is the number of hours a plant kept in sunlight and y is the height in mm.

Since this equation is in the form of equation of straight line y = mx +c in which m denotes gradient of the line and c is y intercept.

In y = 4x + 2, y intercept of the equation is 2 which means when a plant was kept in sunlight its height was 2 mm.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

answer: y=4000x+14000
